A new approach of using the master alloy containing particulate reinforcements to achieve the strength and ductility synergy in the Mg matrix composites was proposed, which can induce the grain size bimodal structure by regulating the dynamic recrystallization (DRX). Specifically, a novel AlN-Al master alloy was prepared via powder metallurgy to fabricate the AlN/ZK60 composite, and the effects of adding the AlN-Al master alloy on microstructure evolution related to the strength and ductility synergy in the composite were thoughtfully investigated, involving precipitation, grain size, and DRX behavior. The reaction between the Al in the master alloy and the Zr in the ZK60 Mg alloy suppressed the grain refinement, and the coarse grains were further formed after the solution treatment on the as-cast composite. Subsequently, deformation heterogeneity between the AlN and Mg matrix during the hot extrusion induced discontinuous dynamic recrystallization (DDRX) and promoted fine grain fraction. The combination formed the bimodal structure in the AlN/ZK60 composite, and coarse and fine grains acted as hard and soft zones, respectively, during the room temperature deformation. The hard zone was enhanced by the basal texture strengthening, and the ductility was improved due to the promotion of the basal 〈a〉 slipping in the soft zone, jointly leading to the strength and ductility synergy in the AlN/ZK60 composite for the ultimate tensile strength increased by ∼7.4 % while maintaining the same elongation compared with the ZK60 Mg alloy.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"105 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the wear resistances of Mg alloys could be deteriorated by increasing the hard particle content in many researches. To reveal the underlying negative effect of precipitate on the wear resistance, the wear behaviors of three AZ-Mg alloys (precipitate contents: AZ31: 2.1 %, AZ61: 3.8 %, AZ91: 5.0 %) at the axial loads of 3 and 15 N were investigated. The results indicated that although wear volume of the AZ-Mg alloys decreased with the increasing Mg17Al12 content at 3 N (0.30→0.24→0.20 µm3) and 15 N (1.04→0.88→0.85 µm3), the relative wear resistances of AZ61 and AZ91 to AZ31 decreased with increasing load (AZ61: 1.25→1.17, AZ91: 1.50→1.22) and the reduction was proportional to the precipitates content (AZ61:7 %, AZ91:28 %). That is because the wear volume of AZ-Mg was mainly attributed to micro-cutting, which was negatively correlated with the precipitate content and tribolayer hardness. However, the wear hardening ability of AZ-Mg alloys was weakened by precipitate for its inhibition on the formation of mechanical twins that the precursors for the tribolayer. Moreover, the inhibition of the precipitate on tribolayer could be amplified by the load, resulting in an increase in tribolayer hardness at 3 N (AZ31: 0.94, AZ61: 1.03, AZ91: 1.10 GPa) but a decrease at 15 N (AZ31: 1.77, AZ61: 1.73, AZ91: 1.62 GPa). Therefore, the formation of twin was inhibited by precipitates, which is detrimental to the wear resistance of Mg alloys. That means the wear resistance could be enhanced by promoting twin formation, which provides a new concept for the design of wear-resistant Mg alloys.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"45 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study provides a comprehensive analysis of microstructure changes in WE43 magnesium (Mg) alloy after laser surface melting (LSM), examining grain morphology, orientation, size, microsegregation, and defects under various combinations of laser power, scan speed, and spot size. Our findings reveal that variations in laser power and spot size exert a more significant influence on the depth and aspect ratio of the keyhole melt pool compared to laser scan speed. Critically, we demonstrate that laser energy density, while widely used as a quantitative metric to describe the combined effects of process parameters, exhibits significant limitations. Notable variations in melt pool depth, normalized width, and microstructure with laser energy density were observed, as reflected by low R² values. Additionally, we underscore the importance of assessing the temperature gradient across the width of the melt pool, which determines whether conduction or keyhole melting modes dominate. These modes exhibit distinct heat flow mechanisms and yield fundamentally different microstructural outcomes. Furthermore, we show that the microstructure and grain size in conduction mode exhibit a good correlation with the temperature gradient (G) and solidification rate (R). This research provides a framework for achieving localized microstructural control in LSM, providing insights to optimize process parameters for laser-based 3D printing of Mg alloys, and advancing the integration of Mg alloys into AM technologies.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"5 2 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples were deformed at two distinct strain levels of 0.05 and 0.10, with tests conducted over different numbers of deformation cycles at each strain level. A detailed microstructural investigation using electron backscatter diffraction (EBSD) revealed that in-plane cyclic shear induced the formation of numerous tensile twins (TTWs) in the alloy sheet. Both the shear strain and the number of deformation cycles contributed to an increase in the twin volume fraction (TVF), which played a critical role in texture evolution. Notably, unlike in-plane shear (IPS) deformation, where two satellite peaks appear in opposite quadrants, in-plane cyclic shear resulted in satellite peaks across all four quadrants of the pole figure. The evolution of texture components across all four quadrants arises from the load variations under forward and reverse loading during cyclic deformation. Thus, in-plane cyclic shear deformation can generate texture components along nearly all directions in the pole figures. Additionally, microstructural and microtextural analyses revealed that TTW is the dominant deformation mechanism, contributing to texture evolution. Furthermore, the resolved shear stress (RSS) analysis indicated that prismatic slip activity predominantly governs dislocation slip behavior.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"35 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143518091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the impact of FSP on the microstructure, mechanical properties, and electromagnetic interference (EMI) shielding effectiveness (SE) of the alloy, specifically across three distinct layers within the stir zone (SZ): Top, Middle, and Bottom. The results reveal that the Mg12YZn long-period stacking ordered (LPSO) phase is the predominant structure, undergoing significant grain refinement. The grain size is drastically reduced from 1.5 mm in the as-cast state to 12.6 µm, 10.0 µm, and 7.1 µm in the Top, Middle, and Bottom, respectively. This grain refinement and fragmentation of the LPSO phase into nanoscale particles result in a substantial enhancement of mechanical properties. The ultimate tensile strength (UTS) reached 358.2 MPa with an elongation (EL) of 15.1 %, reflecting a 344 % increase in strength and a 733 % improvement in ductility compared to the as-cast material. Simultaneously, the EMI SE was maintained between 70 and 110.4 dB over a broad frequency range (30–4500 MHz). Despite the nanoscale LPSO particles contributing minimally to EMI shielding, the lamellar LPSO structure demonstrated excellent performance through multiple electromagnetic wave reflections within the matrix. These findings underscore the dual benefits of FSP in improving both mechanical strength and electromagnetic shielding effectiveness, positioning this Mg98.5Zn0.5Y alloy for advanced applications in the electronics and telecommunications sectors.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"84 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concretely, the drawing depth is increased by 32 % compared with the as-received sheet at 200 °C. This is because {10–12} tensile twins promote the occurrences of many deformation mechanisms during warm deep drawing, such as slips, detwinning, dynamic recrystallization (DRX) behaviors, etc. Further, based on the different stress states during deep drawing, these mechanisms and their competition relationships, as well as texture evolutions, are systematically studied. Combined with critical resolved shear stress (CRSS) and microstructure evolution, the global Schmid factor (GSF) obtained by quantizing stress states by stress tensor (σ) can accurately predict the activation trend of deformation mechanisms. It is found that the stress states have a reverse influence on the activation trend of the {10–12} twinning and detwinning. The change of stress states affects the competitive relationships between detwinning and DRX, and then affects the process and degree of DRX. The {10–12} tensile twins and large plane strain promote the activation of prismatic slips, and the larger plane strain also deflected the {10–12} twinning lattice. The {10–12} tensile twins and their induced deformation mechanisms can prominently weaken the basal texture and improve the drawability.","PeriodicalId":16214,"journal":{"name":"Journal of Magnesium and Alloys","volume":"37 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143518092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of ZrO₂ on the morphological, compositional, and photocatalytic performance was then compared to the case where ZrO₂ nanoparticles were electrophoretically incorporated into the porous PEO coating.

Experimental results demonstrated an outstanding 99.8 % degradation of indigo carmine within 15 mins, with remarkable multi-cycle stability over five consecutive cycles without significant performance decline. This system demonstrates faster degradation rates and greater durability compared to previously reported catalysts, underscoring its potential for effective and sustainable environmental remediation.

A 57-year-old male patient with pelvic fractures and traumatic shock underwent open reduction and internal fixation with Mg clips. At a six-month follow-up, imaging confirmed fracture healing, clip degradation, and no signs of rebleeding or infection, highlighting their effectiveness in precise hemorrhage control. Unlike traditional titanium clips, Mg clips degrade over time, eliminating the need for removal and reducing infection risks. This innovative approach combines Mg clips with conventional gauze packing, offering a more effective and safer alternative for managing pelvic trauma. Future large-scale clinical trials are necessary to validate these findings and establish Mg clips as a global standard for pelvic fracture treatment.
